No scientific reason, just kinda follow Mike Miller suggestion long time ago at Roundel (BMWCCA magazine tech editor) to do flush every 30kmiles.

Writeups like this have been on www.e38.org for years. The 5HP18, 5HP24, 5HP30 between the 3, 5, 7 and X have pretty similar techniques. The most important is the filling precedure. I sold and just did a tranny swap in a customers 97 740iL yesterday...messy procedure to fill the fluid till it spills out, but the car is finally moving under it's own power now.

hi ... i did my tranny change the oil-filters, the jerky movement is almost gone, just once in a will, not as often as before.......

I've heard that VW/Audi part # G-052-162-A2 is the Esso LT71141 "Green Lable" stuff just repackaged. Although, I've yet to get 100% confirmation. It is very plausible. . .

Another refference for Esso Alternatives: Alternatives to the expensive Esso LT71141 automatic transmission oil

I will be using Red Line D4 ATF when I do my trans serivce. All my other cars take D4 ATF and I've been really happy with Red Line Products.

Do all your other cars call for the Esso LT spec fluid?

My only issue with the D4 is that it is a generic fluid claimed to be suitable for all automatics (Dexron, Esso LT, Ford Mercon, Honda ATF, etc) and also used as a gear lube in transaxles. It isn't certified to any of those standards, that is just Red Line's marketing claim.

I think that the reason there are different specs is because different fluids are optimized for each different application. ZF, GM, and Ford even use different fluids in different designs of their own transmissions. Using one fluid in all of those applications (including using D4 as a gear lube) seems a pretty low-tech approach. Just my $0.02

If it wasn't a suitable functionable equivalent then I don't think Red Line would claim so for marketing purposes.

However, I was able to find Esso LT (VW/Audi version) from one vendor for a reasonable price.

I think these are the exact same fluids.... just different part numbers:

(VW/Audi Spec)
VW/Audi ATF ATF1: Semi-Synthetic, High Performance Fluid (1 Liter) G052162A2 - RM European Auto Parts

(BMW Spec)
BMW ATF Auto Transmission Fluid (1 Liter) Equivalent to: ESSO LT 71141 NOTE: Only for "Green Tag" transmission 83229407807 - RM European Auto Parts

Thoughts????

That is marketing B.S.! Plain and simple. Unless you only keep your cars till the end of the warranty period I would not follow that advice.

If it is on the internet it must be true?

Who is more likely to know what fluid is required for a transmission they designed, ZF or Redline? You are dismissing the published ZF requirement, and putting all your faith in a third party who has something to gain by selling fluid to you.
